- shown, since they are well United States Patent GUIDE lVIEAlN' S FORNON ROTATABLE VALVE LIFTERS Edward Iskenderian, Inglewood, Calif.Application October 30, 1956, Serial No. 619,311 3 Claims. (Cl. 123-90)Objects of invention The object of this invention is to replace rotatingmechanical or hydraulic valve lifters with non-rotating valve lifters,in internal combustion engines, such as used in motor vehicles when thestandard camshaft is replaced with a special high lift racing cam, suchas furnished by the inventor. Non-rotation of the lifters is necessarywhen the lifters are provided with rollers such as disclosed herein, orwhen the lifters are provided with a cam-like lifter face to cooperatewith the camshaft in controlling the valve lift. Since such lastmentioned lifters are well known in the art it is not deemed necessaryto show such a configuration.

A further object of this invention is to provide such lifters that canbe installed by anyone without the use of special tools or doing anymachine work. All prior art non-rotating replacement lifters known to bein use do require some machine work or use separate parts that are not apart of the lifter assembly, for example such as disclosed in mycopending application Serial Number 567,010, filed Feb. 21, 1956. Sinceracing camshafts are usually installed by the car owner it is veryimportant that the valve lifters furnished with the camshaft may bemounted without special skill or tools.

For a more complete understanding of my invention consult the drawingsand the following description, wherein:

Fig. 1 shows a pair of lifter assemblies installed in a section of anengine 10. Both lifters are in their low position, such as when bothvalves are closed, the rollers 2 being in a position to contact acamshaft which is not known and form no part of this invention. Theupper end of the right hand lifter is in section to show how anapertured cup is installed in the top to carry a valve lifter rod. Theaperture is to admit engine oil to the end of the rod resting in thecup.

Fig. 2 is a view of a single litter and roller assembly, the cup beingomitted. The lifter is apertured to admit oil therein. may be omitted ifdesired.

Fig. 3 is a cross section of Fig. 2 showing aperture 4 therethrough toreceive the guide members shown in Figs. 5 and 6.

Fig. 4 is a view of the lifter rod cup as seen in Fig. 1.

Figs. 5 and 6 are views of the guide members shown in the assembly ofFig. 1.

Fig. 7 is a view of the male guide member 6b, showing a portion cut awayat 7 to fit in the aperture 4 which is sized to fit the reduced portionat the end of the guide member at 7.

Fig. 8 is a view of the complete assembly of the guide members, with themember 6b shown in broken lines.

Fig. 9 is a top plan view of an assembly of parts 6. 6a and 6b.

Description of the parts As shown in the drawings, the means to preventthe lifters from rotating comprises two off-set metal stampings and oneflat member 6b. Member 6 has a square-like portion and a key-likeportion, olf-set relative to each other an amount equal to half thethickness of the male member 6b. Member 6a has a square-like portionsimilar to 6, and is oil-set a like amount. The other portion is2,816,988 Patented Aug. 12, 1958 the key-like portion of 6 and has areduced portion as at 7 to fit in the aperture 4. The aperture 4 in onewall of the lifter is sized to permit the full width of the members 6and 6b to pass through it so the reduced end can be inserted in theaperture in the opposite side wall when they are installed as seen inFig. 1. The ends of the guide members can be staked, welded or otherwisesecured in the lifter if desired. The apertures 8 and 8a are to admitengine oil to the guide members.

The lifters are of tubular construction as seen in Fig. 3. The aperturesin each wall numbered 3 and 5 are for admitting oil to a cup-like member12 with an oil orifice 13 mounted in the upper end of the lifter toprovide an oil flow path to a litter rod 11, as seen in Fig. 1, the rod11 being no part of the invention. Each lifter is provided with a roller2 mounted in the lower end to contact a camshaft, not shown, since theyare well known in the art. The small apertures 5 may be omitted ifdesired, and the lower end of the lifter may be provided with a camlikeface instead of the roller if desired. Since it is old to providelifters with a cam-like face it is not deemed necessary to show an Toassemble the guides the member 6 is pressed in the aperture in member 6aas seen in Fig. 8, and the assembly positioned in a lifter as seen inthe left of Fig. 1, the member 6b being positioned in a lifter as seenin the right of Fig. 1. As clearly shown, when the member 6b ispositioned between the spaced members 6 and 6a either member including alifter can move vertically or laterally independently. The dotted linein Fig. 1 shows the left hand member up while the right member remainsdown. Lateral movement is provided to accommodate various spacing of thelifter bores in the engines. The width of the guides is suflicient topermit maximum valve lift without separation of the guides.

While I have described my invention in considerable detail, it is not myintention to limit it to the specific configuration disclosed, since itis quite obvious some changes could be made without departing from thespirit of the invention.

What I claim is:

1. A pair of tubular members having associated releasable guide means,the tubular members being spaced apart, and at least a portion of thesaid guide means being attached to each tubular member, the said guidemeans having means to permit vertical and lateral movement withoutpermitting rotation of one member relative to the other, each tubularmember having a roller attached to one end and having an aperture spacedfrom the roller, a single piece guide member carried in the aperture inone guide member, and a two piece guide member carried in the aperturein the other of said pair of tubular members with spaced apart portionsextending laterally outside of its associated tubular member, the firstof said guide means extending laterally outside of its associatedtubular member and positioned between the spaced apart portions of thetwo piece guide member and freely slidable therein when the tubularmembers are spaced apart a predetermined distance.

2. A valve guide means as defined in claim 1, wherein each tubularmember carries a cup-"like member on one end provided with an aperturein communication with the inside of the tubular member, each tubularmember being provided with at least one aperture adjacent the end thatcarries the roller.

3. A valve guide means as defined in claim 2, wherein the spaced apartportions of the second mentioned guide means are provided with anaperture.
